Let N S 0 -, Fig, be a Loadftone in the Form 
of an oblong right-angled Parallelopipedon, whole 
Polarity is Length-ways, N being its North Pole, e, 
the pricked Line, its Equinodial (or Middle betwixt its 
Poles.) where it has no Attradion, and a its South 
Pole. Let it be bilfeded at tranfverfe to its .Pola- 
rity, or Length. Each of its Frufta (reprefented 
Fig, 2 .) when they are placed too remote to ad on 
each other) will infallibly be pofTelTcd of both Poles 
(with its Equinodial in its Middle) ^as the whole 
Stone was before its BilTedion: And though originally 
the one Fruftum N 2 was all over a North Pole, and 
the other v a- all over a South Pole, while they ad- 
hered to one another, yet now they are divided, and 
placed beyond the Reach of each other’s Vertue, one 
half of the Fruftum N 2 from the Place of its quon^ 
dam Contad 2, to its Middle does inftantly become 
a South Pole, and attrad ftrongly at the Place of Con- 
tad aforefaid, which Attradion is gradually lefs and 
lefs until it is abated to nothing at e. So alfo one 
half of the Fruftum v o-, from the Place of its for- 
mer Contad v to its Middle or Equinodial e, inftantly 
becomes a North Pole (gradually abating in Strength 
from yto^y^ though the whole Fruftum, before its 
Separation from the other, was a South Pole: The 
Polarity being alfo direded the fame Way in each 
JFruftum that it was in it (and the whole Stone) be-
